Frequently asked questions
These are low-dropout (LDO) voltage regulators that provide a stable 3.3V output voltage side. They are used in various electronic devices to manage the Main power supply and consumption.
The KIA78D33AF is perhaps the most commonly used low-dropout (LDO) linear regulator available. Input voltage can range from 4.5 – 15V DC and it outputs a fixed 3.3V at 800mA of current and up to 1.3A of surge current flow.
Simply use a voltage divider comprised of 2 resistors. 1 with twice the resistance of the other. You'll form a voltage divider which will output 2/3 of the voltage (3.3v on the point between the 2 resistors). Choose a Resistor using R2 to be twice as large as R1 (e.g. 10K + 20K ohms) to make a circuit diagram.
A voltage regulator is a circuit that creates and maintains a fixed output voltage side, irrespective of changes to the input voltage or load conditions. Voltage regulators (VRs) keep the voltages from a power supply within a range that is compatible with the other Electronic components.
Connect 12v +ve voltage to 7805 input pin and -ve to 7805 GND pin. You will get the output of 5v at the output side pin. You can also give 12v or 9v as input voltage.
